I have a listcontrol in report mode, and I want the text in a particular column to be right aligned. That is, I want to see the end all the time. I cannot find a way to do this, I thought I had, but all I am aligning is the header. Is there a way to align the contents of the column, or do I need to draw the column myself ? Can I draw just one column ?

I usually just use the designer to set up my list controls and setup column/header properties (title, alignment, and size) at that time. I've never yet had an instance in the programs I've developed where I didn't know how I wanted data aligned/formatted at design time.
Now, one thing I've noticed in general about list controls is that it doesn't seem you can right-align the FIRST column in a list control, but I believe that's a global truth about list controls, and not something specific to WinForms.
If at all possible, I would really recommend doing it through the designer. If it's not possible, I'd still recommend doing one through the designer and then look at the code that is generated and compare it with what you're doing. If you can't figure it out still, post some code that can be commented upon.

Thanks for your advise. I've moved the column along from the first position, and set it up in the designer to be right aligned, all this does is right align the header ( which didn't happen even when I started ).
I'm adding the columns in the designer, and there's a drop down list for text alignment, which I set to 'Right'. This generates the same code I tried to add, something like thelist.Columns.TextAlignment = HorizontalTextAlignment.Right.
Thanks for your help.

If you add Items at design-time (for testing purposes only) through the "Items" collection (you'll have to add SubItems of the first item, just the way list controls work), do these show up right aligned? They do for me when I setup a sample list control through the designer, add columns, and add items. If they show up left aligned, even for fields that you know are right aligned, you've got bigger problems and someone else will have to pipe in with some thoughts (possibly bad COMCTL32???)...
If, then, you run your program, only to see everything left aligned, it's pretty obvious that something else is either resetting or recreating the properties on your control. Expand out all the regions of your code and just search for anything related to your list control, paying special heed to anything that may be happening more than once. If you can't isolate it, in the worst case scenario, you can always delete the object off your form/control, and keep re-compiling/fixing errors until you're sure all the code related to the control is gone, then re-add it. I'm sure someone else has other ideas but these are just the ones I can think of.

Thanks - I did all that, and I get a list where the header text is right aligned, but the text in the actual column is not. I am using XP Pro, FWIW. It looks exactly the same as if I play with the code. I added an item, and added subitems until I got to the right column, made that one really long, and I can read the left portion of it, instead of the right.

Ooops, I misunderstood the original post, when I add really long lines, I experience the same behavior you do. I think what you're looking for is definitely possible, but this functionality isn't even available in the Win32 list control (to my knowledge). About the closest thing you could do with the standard control is to add tooltips.
Other than that, I think your only choice is making your own custom list control.

Yeah, that's what I figured. Thanks for helping me to clarify the point. I guess I'll write such a control towards the end of the project if I find the time. It's my idea, not a specced requirement

This makes no sense to me. You appear to be talking about a business domain and assuming everyone already knows it already.

The code you have given appears to have nothing to do with the user interface. What do you mean by "show"?
I'm having difficulty parsing the word "like". Do you mean "like" meaning "similar to" or "like" as a filler word that is otherwise insignificant?

What is "value" unless it is calculated from somewhere. Calculated from what? Where does value come from anyway?
Sorry, you'll have to be more explicit in your request.

Can anyone help me create a Dental database system for recording patients records, I need help.
I have created the tables using Access, and want to link them to visual studio using a .SQL server, it doesnt have to be anything fancy just a start.
If you can help then email me at email2miles@yahoo.com
Or reply on here.

In short, no, however if you have a specific question in doing so, absolutely. No one on here will do your work for you, however we would all love to help if you are stuck on something specific. There are plenty of articles on CP that cover how to interact with a database, look through the articles and read MSDN[^] as well.

These are two different database technologies. Which do you want to use Access or SQL Server?

yea i have designed the access part, and i think i have just linked it so i can view the tables etc in the server explorer, but this was using jet 4.0 provider.
YOu think i am alright using that?
Now i wanna design some forms and get some queries running, any advice?

I don't know that depends on what you are trying to achieve. Access is good as a desktop database with a limited number of users. SQL Server is good at being a server database with many users. Access has lots of built in functionality to allow whole applications to be built with it. SQL Server provides functionality that supports its use in a n-tier environment. If you are not using the application side of the Access database, MSDE may be a better choice as it is a cut down version of SQL Server that supports a limited number of users, but integrated just like the full SQL Server. You can also create Stored Procedures with SQL Server which mean that you get an extra layer of protection as your application interacts with the Stored Procedure rather than directly with the tables.

I am assuming you mean Windows.Forms rather than the forms in Access. However I don't know what you are looking for in advice - the design aspect is entirely dependent on what you need to achieve.
You should think about the types of things that need to be recorded at certain stages of the service (e.g. when a patient arrives for an appointment, when the dentist requests a follow-up appointment, the patient calls to cancel/rearrange an appointment). This is where Use Cases come in handy. If you don't want to go to the formality of Use Cases then you can just think of lots stories where an interaction with the system occurs, where does information come from, who interacts with the system you are building, what are the outputs (e.g. Is it just an update in the database, or is an invoice printed or whatever). Once you have these stories you can begin to see what forms you will need to design and what to put on them. Some stories may overlap somewhat and you might be able to design a form that fits into two or more stories.
Does this help? If not, you may need to be more detailed in what you are trying to achieve.

Yes i mean windows.forms, i have a scenario written out and want a way to record details of the patient etc and tell him/her when there next appointment will be. I dont want it to print, however if i have time i can introduce an appointment card.
Firstly i bought the wrox press beginning c# databases book and that loads an employee database up which you can run queries select etc.
I need to know how i can do that using my dentist access database, so i can design forms and select different patient records and add new patients in.
Its difficult to explain, should i send you my access database first?

Some questions:
1. Is this your first ever C# program ?
2. Is this your first ever database program ?
3. Is this your homework ?
As has been said, Access and SQL Server are two different things. SQL Server obviously canes Access, but if you're only doing something simple, Access has some benefits, some of which can be achieved with MSDE. For starters, if this is not homework, and if someone is actually going to use this code, do they have a licence for SQL Server ?

OK, well, a DataGrid provides out of the box Excel like editing for a data source, and with articles on this site you can add drop down lists that reference lists in your data. As has been said, Access and SQL Server are two very different beasts. If it's for a computing degree, I recommend using SQL Server, seeing as it is useful in the 'real world'. Apart from that, you'll need to be more specific. What does your database schema look like ? What information do you need to store in it ?

i have a problem some parts of the image of the form still on the screen after i close the form which affect the form under it
|

1.Are you using API function LockWIndowUpdate(hwd handle)any where in the code???
Please make sure that window should get unlocked, before closing the form.
2.If you are not using LockWindowUpdate, then as Mr. Nick has recommended, you should Invalidate the region behind the form.
I have had this problem due to LockWindowUpdate, that is why I added the point.
Hope this helps.

merci for reply
1- i don't call any api function in my code it is all C#
2- i know the solution of Invalidate but i think that the under form must be restore with out using invalidate to invalidate the region behind the form

I'm trying to creat a program that will scan a directory for all image files and add them to a list box. I have that all under control. However when I select 5 megapixel pictures which can be over 2 meg a piece the program will have extreme difficulties. I tried using it and selected 40 some 2 meg pictures to turn them into thumbnails by simply resizing them. However my PF usage went to over a gig! So what can I do to create a thumbnail of these pictures without a 1 gig PF usage?

When you are done with your Bitmap object, explicitly call Dispose(). Alternatively, when you create your Bitmap object, use the C# using syntax which will emit a try/finally block around your code and in the finally statement it will cast your Bitmap object to an IDisposable and call the Dispose() method for you. You can only use the using syntax when the object you create implements the IDisposable interface. The syntax would look as follows.
using(Bitmap b = new Bitmap(16, 16))
{
}
